Answer:
B 5 seconds
Step-by-step explanation:
h = 240 + 32t – 16t^2
When is this equation 0
0 = 240 + 32t – 16t^2
Factor out 16
0 = -16(-15-2t+t^2)
= -16(t^2-2t-15)
What 2 numbers multiply to -15 and add to -2
-5*3 = -15
-5+3 =-2
0 = -16(t-5) (t+3)
Using the zero product property
t-5=0 t+3=0
t=5 t=-3
Since time cannot be negative
t=5 seconds
Answer:
The answer is 15/37.
Step-by-step explanation:
There are 15 girls who like starwberry icecream, and the total of girls is 37.
So, the ratio of girls who prefer strawberry icream to the whole group of girls, 15 out of 37 (15/37 or 15:37) like strawberry icecream.
Answer:
The distance between the points is approximately 6.4
Step-by-step explanation:
The given coordinates of the points are;
(2, -2), and (6, 3)
The distance between two points, 'A', and 'B', on the coordinate plane given their coordinates, (x₁, y₁), and (x₂, y₂) can be found using following formula;
Substituting the known 'x', and 'y', values for the coordinates of the points, we have;
Therefore, the distance between the points, (2, -2), and (6, 3) = √(41) ≈ 6.4.
Answer:
The fourth graph.
Step-by-step explanation:
We have f(x + 1) so the x values will be increased by 1.
first value = 108 (when x = 1)
next value = 108 * 2/3 = 72 (when x = 2)
next = 72 * 2/ 3= 48 (when x = 3)
next = 48 * 2/3 = 32 (when x = 4)
